Why is funkey kong the only character used?

He has the highest speed stat in the game. Funky with the Flame Runner is considered to be the most OP combo sense most of the world records in MKWii use this combo. Daisy with the Mach Bike is up there too.

thank you. i forgot that characters have small variations in stats. what's with funky being op in games?

He's funky. He's a funky kong.

I use King Buu, it is a good character?

Unfortunately, King Boo is the worst one to use of the heavy characters. These links may be able to help you guys: https://4drclanforum.com/threads/mario-kart-wii-tier-list.1364/ https://gamefaqs.gamespot.com/boards/942008-mario-kart-wii/60063231
